Metastatic cancer accounts for most cancer-related deaths, and identifying specific molecular targets that contribute to metastatic progression is crucial the development of effective treatments. Hypoxia, a feature solid tumors, plays role in by inducing resistance therapy accelerating metastasis. Here, we report CCAAT/enhancer-binding protein beta (C/EBPβ) transcriptionally regulates hypoxia-inducible factor 1 subunit alpha (HIF1A) thus promotes migration invasion non-small-cell lung (NSCLC) cells under hypoxic conditions. Our results show knockdown or forced expression C/EBPβ was correlated with HIF-1α directly bound promoter region HIF1A. Silencing HIF1A inhibited enhanced induced overexpression NSCLC hypoxia. Expression target gene, SLC2A1, also altered C/EBPβ-dependent manner, SLC2A1 reduced overexpression. These indicate critical regulator tumor microenvironment. Collectively, C/EBPβ-HIF-1α-GLUT1 axis represents potential therapeutic preventing improving patient outcomes.

Background Prostate cancer (PCa) is one of the prevalent malignant tumors among men. It can progress to castration-resistant prostate (CRPC), which significantly more challenging treat. Saikosaponin A (SSA), a triterpenoid saponin extracted from genus Bupleurum, exerts numerous pharmacological effects, including anti-inflammatory and anti-tumorigenic effects. However, mechanism underlying effects SSA in treatment remains elusive. Methods In this study, network pharmacology approach was applied identify relevant targets drug- disease-related databases, intersections were analyzed using Venny2.1 construct Protein-Protein interaction (PPI) network. Next, Gene Ontology (GO) Kyoto Encyclopedia Genes Genomes (KEGG) enrichment analyses performed elucidate associated biological functions signaling pathways. Meanwhile, molecular docking between core Autodock software. Lastly, vitro experiments for validation. Results least four key targets, namely BCL2 apoptosis regulator (BCL2), estrogen receptor 1 (ESR1), hypoxia-inducible factor subunit alpha (HIF1A), signal transducer activator transcription 3 (STAT3) identified revealed that stably binds these targets. Moreover, results inhibited proliferative migratory abilities PC3 cells dose-dependent manner. Finally, also induced G1-phase blockade cells, further highlighting its potential role treatment. Conclusion The present study by targeting multiple pathways, laying theoretical reference use as therapeutic candidate cancer.

Summary: Ovarian cancer (OV) remains the most lethal gynecological malignancy. The aim of this study was to identify molecular subtypes OV through integrative multi-omics analysis and construct machine learning-based prognostic models for predicting efficacy immunotherapy. In here, mutation, copy number variation, RNA sequencing expression profiles, clinical information were obtained from Cancer Genome Atlas (TCGA) Gene Expression Omnibus (GEO) databases. Multi-omics data stratified using MOVICS package, identifying different subtypes. Our identified 2 (CS1 CS2) with significant survival differences. Transcriptional regulatory network revealed differential activation transcription factors such as FOXA1 GATA3 in CS1, whereas AR ESR2 enriched CS2. A robust signature comprising 5 key genes developed integration 10 learning algorithms, demonstrating high predictive power across sets. Immune cell infiltration that anti-tumor immune cells more abundant low-risk groups, pro-tumor predominated high-risk groups. Furthermore, patients exhibited better immunotherapy responses higher tumor mutational burden (TMB). conclusion, our findings underscore potential unveiling novel constructing inform personalized treatment strategies. Future research should focus on validating these larger cohorts enhance management targeted therapeutic approaches.

Nasopharyngeal carcinoma (NPC) presents a significant medical challenge due to its high incidence rate and poor prognosis, which are attributed primarily tumor metastasis drug resistance. Sine oculis homeobox homolog 1 (SIX1) has been identified as crucial target for cancer treatment. However, role in NPC remains incompletely understood. This study investigated the mechanisms by degradation of SIX1 protein, is mediated ubiquitin, affects malignant characteristics throughout cell cycle. Our findings reveal that reduced expression itchy E3 ubiquitin ligase (ITCH) impedes leading enhance oncogenic properties. Knockdown experiments was inhibited demonstrated decrease proliferation, migration, invasion lines, whereas overexpression yielded opposite effects. Further experimental validation revealed promotes progression via division cycle 27 (CDC27)/cyclin B1 axis. These provide valuable insights into potential therapeutic targets prognostic indicators treatment, emphasizing ITCH/SIX1/CDC27/cyclin axis promising novel therapies.

Breast cancer is a major public health concern worldwide, being the most commonly diagnosed among women and leading cause of cancer-related deaths. Recent studies have highlighted significance non-histone methylation in breast cancer, which modulates activity, interaction, localization, stability target proteins. This regulation affects critical processes such as oncogenesis, tumor growth, proliferation, invasion, migration, immune responses. review delves into enzymes responsible for methylation, protein arginine methyltransferases (PRMTs), lysine (KMTs), demethylases, explores their roles cancer. By elucidating molecular mechanisms functional consequences this aims to provide insights novel therapeutic strategies targeting these pathways. The potential overcome drug resistance enhance treatment efficacy also discussed, highlighting promising avenues future research clinical applications.
